This problem happens due to low levels of vitamin B1 (thiamine). Alcohol use disorder is the most common cause. It prevents the body from getting enough of this vitamin.

Other causes may be:

  • Eating disorders
  • Long term vomiting
  • Mental health problems
  • Chemotherapy
  • Cancer

Genes may also play a role.

Risk Factors

This problem is more common in men. It is also more common in people who are 50 to 60 years of age.

Other things that may raise the risk are:


Severe memory problems are the main symptom. A person may have a hard time remembering recent events and new information, such as today's date. People may make up information to fit a given situation.

Other problems may be:

  • Confusion
  • Learning problems
  • Problems communicating
  • Trouble focusing
  • Problems with walking and balance


The doctor will ask about your symptoms and health history. A physical exam will be done. Memory function will be tested. This can be done with neuropsychological testing.

Images of the brain may be taken. This can be done with an MRI scan.


Underlying causes will need to be treated. For some, this will mean not drinking alcohol. A rehabilitation program can help.

The goal of treatment is to ease symptoms and stop the disease from getting worse. Nutrition counseling and thiamine supplements may be used.


Korsakoff syndrome often happens after a person has had Wernicke encephalopathy. The risk of this problem can be lowered by:

  • Getting enough thiamine from food sources
  • Limiting alcohol
